ACETYL'ENE-GENERATING APPARATUS.

Application filed December 24, 1919. Serial No. 347,117.

To all whom it "may concern.

Be it known that 1, JOHN S. NOEL, a citizen of the United States oi America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Acetylenc- Generating Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an acetylene genorator. It a primary object and purpose of the present invention to make a generator in which, when the carbide falls into the water, it :talls within a cylindrical casing or mixing chamber, the upper end of which. always passes a distance into the lower end of the gas bell, and the lower end of which while open in construction is soon closed by sediment deposited from thecarbideso that no gas is lost by escape from the water around and. outside of the gas bell, all of: the gas being generated within said mixing chamber and going directly therefrom into the gas receiving bell. This provides insurance against loss of gas and against the necessity of completely charging all of the water within the generator and super-satuating the same so that gas will arise therefrom to the gas bell. A further object and purpose of the invention is to provide a novel cooling chamber at the bottom of the generator into which the gas is led after filtration and in which it is held for a time before passing outwardly to be used. The cooling chamber is a reservoir to hold the outgoing gas for a time before use, it being cooled while thus held. A still further object of the invention is to provide a generator in which the sediment deposited from the carbide may be very conveniently removed without the necessity 01 at the same time, removing the whole or a major part of the charged water in which the sediment is deposited, this tending to economy in operation of the generator as a considerable amount of carbide consumed in saturating fresh water before any gas rises therefrom for use.

All of these various features of utility together with man others not specifically stated at this time, appear and the constructions for attaining the same are fully disclosed in the following description taken in connection with the accompanying draw ings, in which;

Fig. 1 is a. vertical section through the complete assembled generator.

Fig. 2 is a similar section, the cover for the outer casing or the well, the gas bell and the carbide holder being removed for the ready insertion of the sediment removing pumping outfit.

Fig. 3 is a horizontal section taken on the line 33 of Fig. l; and

Fig. 4 is a fragmentary perspective and sectional view of the lower part of the generating apparatus.

Like reference characters refer to like parts in the different views of the drawings.

The generator comprises the usual outer casing or well 1 of sheet metal which has a bottom 2, the upper end of the well being normally closed by a removable cover 3. This well is cylindrical in form, preferably. In the bottom of the well a hollowcooling chamber orreservoir is positioned, being comprised of two arms at, and an additional longer arm 5 disposed at angles to each other as shown in Fig. 3. On this cooling reservoir member a cylindrical casing 6 of sheet metal is positioned being open at both ends and resting at its lower end on the arms 4 and 5. Pipes 7 thread at their lower ends into the arms t and 5 and extend upwardly above the casing 6, having threaded connection at their upper ends with a channel shaped ring 8 in which filtering material 9 is placed.

The carbide holder 10 rests on the ring 8. It is provided with a downwardly and inwardly inclined bottom 11 of substantially funnel shaped form on which the carbide 12 is carried. An opening is made at the lower end of the tunnel and a rod 13 extends vertically through this opening and through the top of the carbide holder having a 'alve head l t at its lower end which in upper po sition closes the opening in the bottom of the carbide holder and prevents the escape of carbide. A lever 15 is pivotally mounted between its ends on the top of the carbide "which pipe the gas may be taken and used "addltlonal gas.

holder and at one end has pivotal connection to the rod 13, the opposite end being equipped with a weight 16, the effect of which is to normally elevate the valve 14 and prevent the escape of carbide.

A gas bell 17 having a closed upper end 18, is located within the well 1 and is freely mo *able up and down within the same. The

diameter of the bell 17 is greater than that of the carbide holder 10, the ring- 8, and of the casing (3 so that it passes down over the same as shown in Fig. 2. The lower end of the bell extends into the water which is normally kept at a level slightly below that of the upper end of the casing. It is evident that the weight of the gas bell normally tends to carry it to a lower position such that the top 18 willstrike the upper end of the rod 13 thereby moving the rod downwardly and permit the escape of carbide into the water from which gas is generated andreturned to the bell. Upon generation of a suflicient amount of gas the bell is lifted above the rod 13 and the escape of carbide to the water stopped. lVhen the gas is to be used it passes from the bell through the filter 9 and down the'pipes 7 into the spaces within arms 4: and 5 from which it passes outwardly through the outlet pipe 19 attached at the end of the longer arm from for any desired purpose. With the passage otgas from the hell it lowers and again operates the rod 13 to allow the passage of carbide to the water and the generation of Accordingly. as long as there is carbide in the carbide holder the supply of within the bell 7 remains practically constant.

From the carbide a sediment is deposited in the water. This sediment indicated at 20 and ma short time fills the spaces between arms and 5 and closes the lower end ot the cylindrical casing 6. Thereafter no vgas can go to the *ater outside of the eas 111g 6 and there 13 no rising and loss of gasthe water between the walls of the gas belland the well 1.

themethod of and apparatus for removal in Fig. 2. The cover 3 is removed and the tially into the sediment. The sediment may be freely pumped from the bottom of the casing 6 by operating the pump 22 and the greater portion thereof removed without} affecting or removing the water; in fact, very little or no water will be removed as I This sediment must be removed at tunes and I have shown mana e the sediment is removed, and this is of value as the water should be left in the well if possible, inasmuch as several pounds of carbide are required to charge and saturate fresh water before gas will escape therefrom to the gas bell. In removing the sediment it is not desirable to remove all of it, particularly that which is deposited between the arms atand 5 of the cooling reservoir. This sediment left. seals the bottom of the casing 6 and precludes any waste of gas through escape from the water outside of the casing 6.

This construction of generation is comparatively simple and has proven very practi -al and serviceable in use and operation. The invention is defined in the appended claims and I consider myself entitled to all modifications in structure which fall within the scope of said claims.

' I claim:

1. A device of the character described comprising an elongated vertically positioned well, a fiat hollow reservoir in the bottom of the well comprising a plurality of connected arms, pipes threaded unto the arms and extending upwardly therefrom, a casing surrounding the pipes within the well and resting at its lower end on the arms of the reservoir, a carbide container supported at the upper end of the pipes, a gas bell located within the well and covering the carbide container and extending downwardly beyond the upper end of the casing, means for automatically feeding carbide from the cont-amen" as the supply of gas within the gas bell diminishes, said gas from the gas bell passing through the pipes into the hollow reservoir, and an outlet pipe connected to one of the arms of the reservoir at the end thereof outside of the casing and gas bell, substantially as and for the purposes described.

an elongated vertically positioned well, a

hollow cooling reservoir located in and resting on the bottom of the well and comprised of a ')l.urality of connected radiating arms, one of which is longer than the others, pipes connected to the arms and extending up- 'ardly-thereform. a hollow ring at the upper end of the pipe to which said pipes are connected, a carbide container supported by the ring, a gas bell located within the well and passing downwardly over and covering the carbide container and extending a distance below the same. and an outlet pipe connected to the outer end .of the longer arm of the reservoir and passing upwardly in the well between the side thereof and the gas bell, substantially as described.

In a device of the character described, an elongated vertically positioned well, a hollow reservoir resting on the bottom of the well and comprising a plurality of radial arms through which gas generated passes and is held and cooled before use, a casing open at both ends and restlng at lts lower end on sand arms of the reservon, a carblde container located directly over the upper end of the casrng, whereby carhlde 'dellvered theretrom drops wlthln the casmg and sedlment from the carblde fills the spaces between the arms and lower partof the casing, and an outlet pipe connected to one arm of the reservoir at a point outside '10 off the casing", substantially as described.

In testimony whereof. I atfix my signature.
